Customer Questions & Answers

Hello, Will I be able to use this with an oil burning boiler?

Asked by: Elizabeth
No. The burner circuit voltage on this is 24 volts. This is for a gas burner. You need a 120 volt burner circuit. Honeywell makes many aquastats. The cover shows L8148E. There are 4 numbers after L8148E that determines the type. There should be a small label attached to top or bottom of the aquastat showing the full number.

Rated 1 out of 5 by from Aquastat Relay Type L8148E This product is not worth buying. I replaced it twice and now right after the warranty expires the relay box does too. I am looking into a different model because i am not going to keep spending $200 +
